This invention relates to a washing apparatus designed primarily for useas a dish washer, but it is to be understood. that the apparatus is foruse in any connection for which it may be found applicable. I

The object of the invention is to provide, in a manner as hereinafterset forth, an apparatus of the class referred to wherein the washingoperation is carried out by a cleansing medium agitated by compressedair.

A further object of the invention is to provide in a manner ashereinafter set forth, an apparatus of the class referred to soconstructed and arranged to provide for the articles which are to bewashed thereby. cleaned solely by the action of a cleansing fluid undera state oi agitation caused by compressed air circulating around thearticles thereby overcoming the necessity of the use of the hands of anattendant during the washing operation. t

A further object of the invention is to provide, in a manner ashereinafter set forth, an apparatus of the class referred to which iscomparatively simple in its construction and arrangement, strong,durable, compact, of cabinet type, thoroughly efficient in its use,expeditious in its operation, conveniently controlled, readily assembledand comparatively inexpensive to set up.

In the drawings:

Figure 1 is a front elevation of the apparatus,

Figure 2 is a longitudinal sectional view thereof Figure 3 is asectional plan,

Figure 4 is an inverted sectional plan, and 9 Figure 5 is a fragmentaryview in section and in elevation looking towards one end of the tank orwashing chamber.

The apparatus includes a portable cabinet in which is to be arranged theother elements thereof and cabinet 5 will preferably be of theconstruction shown, but it is to be understood that any suitable form ofcabinet or housing in which the other elements of the apparatus may bearranged may be substituted for cabinet 8.

The body of the cabinet includes walls and a top and bottom l3 to Hi,also rectangular lower and upper frames l9 and 20 and a rectangularconfiner 2|. The frame 20 is arranged against the inner faces of thewalls and in proximity to the upper ends to support the tank. Flanges 22to 25 also form supports. The top ll rests on confiner 2| and on thewalls and has handle 28 and hinges 26, 21.

Suspended withinthe cabinet body is an open top tank or receptacle 32 inwhich the dishes to be washed, rinsed and dried are arranged. As

shown tank 32 has arranged therein a body of a cleansing medium 33 inthe form of a fluid which preferably will consist of very hot water anda strong soap. The level of the medium 33 will be below. the top of thetank. Preferably the tank will consist of a body lined with porcelainto'prevent the medium 33 attacking it whereby the life of. the tank willbe enhanced. The top of tank 32 is formed with an outwardly directed.endless flange 34 disposed at right angles to the tank body 35 andpositioned in the space between the flange 25 of frame 20 and theconfiner 2I.' The height of tank 32 is less than .that of the chamber 36provided by the cabinet. The flange 34 in connection with the flange 24of frame 20 and confiner 2| connects the tank to the cabinet andsuspends the tank in theupper portion of chamber 36 in spaced relationwith respect to the bottom I! and walls of the cabinet.

The rectangular confiner" 2| rests upon the upper side of the flange 34'of. the tank and may consist of strips of appropriate dimensions toreach around the inside of the walls and from the flange to the tops ofthe walls. In connection with the said walls, it serves to support thecover l8. It also forms the edges of a free space above the tank andbelow the cover which may receive excess foam and suds thereby assistingin preventing same from over-running the top and sides of the tank andeasing. This confiner may be connected to the flange oi. the tank by anyde-* sired holdfast means. 1

The casing has an entirely closed bottom 11, supported on legs I and 8and supported upon the bottom i'l below the tank 32 is an'air compressor45 and an electric motor 46. Leading from the latter to compressor 45 isa power transmitting means 41 in the form of an endless belt for drivingthe compressor. The latter is provided with a compressed air dischargepipe 43.

Pipes numbered 43, 44 and 48 to 51 lead from the compressor to the tank.These pipes carry compressed air for agitating the contents of the tank.51 is a support. Faucet 29 to 3| and 38 leads from the bottom 32 of thetank and doors 58 are provided for the cabinet.

The dishes or utensils are cleaned by the agitation of the cleansingmedium due to the circulation of the compressed air around the dishes.The tank is substantially filled with a cleansing solution formed ofhot' water and soap. Any commercial saponaceous material, may be used.The compressed air provides for the soap solution to clean the disheswithout the necessity of the hands. entering the solution during thewashing operation. Rinsing may be accomplished by withdrawing thesolution from the tank and applying a rinsing water agitated by thecompressed air. After the dishes have been rinsed, the water iswithdrawn from the tank and the dishes subjected to the compressed airfor drying them.

Having described the device as above set forth, what I claim is: a

A washing apparatus structure oi. the class described including anelongated closed cabinet, an elongated tank within the upper part of thecabinet for receiving articles to be washed together with an agitatablecleaning solution therefor, the

tank having an outwardly extended flange at its top, a frame below thetop of the cabinet and attached thereto for supporting said flange andtank, a rectangular confiner resting on said flange and a hinged coverclosing the tank and cabinet and resting on the external walls of thelatter and on said confiner, providing a free space between the top ofthe tank and the cover, an entirely closed bottom for the cabinet, amotor and air compressor supported on said bottom immediately below thetank, and a compressed air pipe leading from the compressor to supplyair for agitating the contents of the tank.
